2″-60″150LB~2500LB Check Valves High integrity Sealing With Valve Structure
2"-60"150LB~2500LB Check Valves High integrity Sealing With Valve Structure
- The disc returns to the sealing position with the force of spring and sub-pressure caused by medium flowing. Direct impact of the medium onto the back side of the disc. - Axial flow structure and accurate flowing passage enable little pressure loss, stable medium flowing, and non-cavitation erosion. - The special structure and surface treatment of the disc carrier and pin eliminates the phenomenon of valve sticking so that it can close and open. - Low-noise type. - Widely used in the pipeline system with high flow requirements to prevent the harm of liquid flow back. - Designed according to API 6D and ASME B16.34.
